Enhancing Security for Mobile Ad hoc Networks by Using Identity Based Cryptography

Abstract

This paper studies key management and security issues in mobile ad hoc networks (MANETs). Lack of strong identification results in unauthorized entities access to the sensitive data, and leads to loos of confidentiality and integrity, which causes many vulnerabilities and attacks in the network .We present the key management scheme as a combination of Identity-Based (User’s Identification), Unique Transmission’s time Factor and Threshold Cryptography for ad hoc networks. It is a certificateless solution which eliminates the need for public key distribution and certificates in public key management schemes. This scheme is also efficient in computation since small unique factor enhance the authentication of entities.
